Abstract

A liquid reservoir portion 38 in which coating liquid is accumulated is formed in a right-left direction in an upper surface 18 of a first body 112 of a die 10 . A shim 16 has a back piece 46 arranged on the upper surface 18 in back of the liquid reservoir portion 38 , both right and left pieces 48, 50 arranged on the upper surface 18 on both right and left sides of the liquid reservoir portion 38 , and a plurality of comb tooth pieces 52 arranged on the upper surface 18 in front of the liquid reservoir portion 38 and extending in a front-back direction. The plurality of comb tooth pieces 52 are fixed to the upper surface 18 positioned in front of the liquid reservoir portion 38 at predetermined intervals.
